PORTABLE COW-MILKER.

Specicaton of Letters Patent.

Patented May 25, 1920.

Application filed November 25, 1914. Serial No. 873,939.

To all whom it may concern:

Be it known that I, WILLIAM M. MEHRING, a citizen of the United States, residing at Keymar, in the county of Carroll and State of Maryland, have invented certain new and useful Improvements in Portable Gow- Milkers, of which the following is a specification.

My invention relates to an improvement in portable cow-milkers, the purpose being to provide means for milking several cows, three or more, at one time and with the use of a single pulsator, and so arranging and equipping the apparatus that it may be easily shifted and cleaned. Also it saves much piping in the stable, and is therefore economical.

With these objects in view, this invention consists in a pipe with means on which it rests upon the iioor or ground, or could be suspended from ceiling or wall, and provided with flexible hose with teat-cups, and provided with valves or cocks to control the flow of milk to the main pipe. The invention further consists in a supplementary extension-pipe with hose connections, making it possible to milk a number of cows more remotely located from the can or. receptacle without the necessity of moving the latter.

The invention further consists in certain novel features of construction and combinations of parts, which will be hereinafter described and pointed out in .the claims.

1n the accompanying drawings :-I

Figure 1 is a view in perspective, showing my improved portable apparatus with five cows being milked;

Fig. 2 is a view showing the supplementary extension,

Fig. 3 is a view of one of thc legs on which the main pipe is supported; and

Fig. 4 is a view of one of the rests for the support of hose and teat-cups when removed from the cow and not in use.

A, represents the main pipe, which may be braced if desired, asshown, to prevent its bending easily; and l, 1, are the flexible extension-hose leading from outlets 3, 3, on the main pipe, each of which preferably has a valve or cock 4, and on the outer end each flexible hose is provided with the usual teatcups 5, 5, for attachment to the cows udder. The valves o'r cocks 4 may be omitted, and theteat-cups provided with cocks 6, 6, or their equivalents, or it is possible to use both cocks 4 and 6, if desired.

'The pipe A is supported on legs T, 7, these being of any approved form, preferably A- shaped as shown, braced across at the lower end by the rod or bolt S, and secured to the pipe at the upper end by embracing clamps 9, 9, and bolts or screws 10, 10. If desired, a lateral arm 11 may be provided also on one of the legs, having a clamp 12 upon the pipe A at a short distance away from the clamp 9 to hold the legs rigidly in place.

At intervals, the forks 13, 13, are mounted on the pipe A by means of clamps 14, 14, and with the upper ends of these forks the hose and cups are adapted to be raised, when not in use, to keepthem off the ground. A receptacle, C, of any sort desired, such as a can, may be used to receive the milk.

A pulsator 15 may be coupled directly to the pipe A, as shown at the right-hand end thereof in both Figs. 1 and 2, or might be mounted directly on the can C, if desired, as shown in the dotted lines in Fig. 1.

A supplementary extension-pipe 16, as shown in Fig. 2 is preferably supported on rests 17, 17, to hold it away from the ground. and liexible hose 18, '18, connect the ends of this pipe with the main pipe A at one end, and the can C at the other.

From the foregoing `it will be seen that the entire row of cows from three to five or more may be milked simultaneously b the use of a single pump (not shown through the-suction applied to pipe 20, and into a common can C; and instead of the parts being stationary they are all portable; and instead of the pulsator being required for every two cows, a single pulsatoi will sutiice for the entire number; and, by having it located on the pipe or can, it is portable along with the other parts of the ap paratus.

Thus is provided an apparatus which will niilk a number of cows simultaneously, which is easy to install and milks rapidly, and is easy to move from place to place, as well as being perfectly sanitary, as the straight rigid pipes A and 16 make it perfectly easy to run a swab through to clean them after milking.

Obviously several cans could be used instead of one, but it is perfectly feasible to use a large can and thus save repeated emptying of the latter.

The operation is as follows:-Tlie motor which operates the air pump is started, and the valves on tlie pipe A are first closed. Then as the apparatus is applied to the cow, the valves connected with tlie hose and teatcups are opened, and the suction applied through the pump holds the. cups in place. The other cups are placed on in like manner. The suction draws milk from the udder, and the pulsator breaks the vacuum partially, or Wholly, as is desired, which relieves the 'cow of constant suction, and simulates the action of' the calf in getting the milk.

Whenva coW is milked, the valves are closed, and the hose hung upon the hook or fork. When all are milked, the hose is uncoupled from the can, the lid may be removed, and the milk removed, or it may be 's replaced by another can. When required,

the extension-pipe is attached, and the apparatus moved to the next set of cows to be milked.

In Asmalll dairies, it may be more convenient not to use an extension-pipe,- but-to move the can when empty to the next position, and to attach to the vacuum-pipe, Whiclishould be placed at convenient points in the stable;

4 herein seti` forth, but z- It is evident that 1more or'less slight' changes might be made in the form and arrangement of theseveral parts described without departure from the spirit 'and scope ofimy invention, and hence l do not vvish to be limited to the exact construction I; claim l.
